JOURNAL BOX Filed DeC. 8, 1951 il@ IIIIIIIIIIIIIIIII /N VEN TOES;FICHA/Qa IBR/rung] AND CHARLES W KIs/f. By M42 NSmombh H/S ATTORNEY erend of the conical wall is centrally bored to surround the sleeveportion 'i2 in spaced relation and is located in spaced relation to theshoulder 1l and spaced from a snap ring 8l demountably secured on theend 0f the sleeve portion 12 to hold the parts together as a unithandling thrust assembly. An annular projection 83 extending from thewall 8G and beyond the end of the sleeve portion 12 has a flat annularend face against which shims 85 are held by a cap 86 demountably fittedover the projection 83 and engaging a boss 81 in the end wall of thejournal box l2 (Figure ll).

The conical cushion 18 comprises an annulus of synthetic rubber or othersuitable yieldable material inherently and deformably resilient in alldirections and which will not deteriorate in the presence of oil.Conical outer and inner metal reinforcing sleeves 9U and Si arepermanently bonded as by cement or vulcanization to the outer and innerconical walls of the cushion, these sleeves seating respectively againstthe conical walls 16 and 58. The outer cushion periphery terminates inan annular nose portion engaging the radial wall 313 and the innercushion periphery terminates in a similar nose portion engaging the face10. Each of these reinforcing sleeves terminates at one end in spacedrelation to the nose portion which continues therefrom and at its otherend extends beyond the cushion. The aggregate thickness of the shims 85is preferably chosen to provide an initial preload on the cushion 18which locates the thrust block 42 against the recess walls 59. Under endthrust of the axle l0 against the thrust block, Athe ends of the cushion18 first deform to yieldably absorb light endwise load. As the endthrust of the axle increases, this thrust is correspondingh7 andresiliently resisted as the cushion longitudinally deforms under a shearstress wherein the reinforcing sleeve 9i axially moves with respect tothe reinforcing sleeve 95. Due to the swivel movements of the members 58and the longitudinal and free tilting movements of the feet 54lengthwise oi the recesses 51, the resiliently deformable character ofthe cushion 18 assures an even engagement of the facing member 41against the flat end of the axle Hl. The extreme movement of the axletowards the thrust block is finally limited by the abutting of thesleeve portion 12 against the boss 81.

The thrust assembly is installed as a unit through the box opening byvertically lowering the assembly into the box with one of the feet 54entered rst, the swivel bushings 5B and cover plates 6l having beenremoved. After the assembly is completely entered, it is turned tolocate both arms 52 horizontally. The swivel bushings 58 are theninserted in the bores B0 with the recesses 61 receiving the pins 66 andthe feet 54 are located in the recesses 51 after which the cover plates6I are secured in position. If necessary, a suitable tool such as asmall bar may be used between the rim of the opening 35 and the arms 52to overcome the initial preload in entering the feet 54 in theirrespective recesses.
